The design was prepared at Horwich but featured a number of Derby features such as cab, bunker and boiler fittings as well as a Derby boiler which made the engine look distinctly like the Fowler 3F 0-6-0 “Jinty”. The engines were built at Derby and the first five of the class were sent to Scotland while the remaining 5 were dispatched to Fleetwood and Birkenhead. The class was able to negotiate curves of two and a half chains by use of a very short wheelbase and a Cartazzi self-centring axlebox on the rear axle. Due to this arrangement inside Stephenson valve gear was somewhat impractical so outside Walschaerts valve gear was provided with short travel slide valves above the cylinders. Withdrawals of the class began in 1959 with the final member 47165 being retired in 1964. www.MeshTools.co.uk 2 Technical data – LMS 2F 0-6-0T Dock tank: Introduced: 1928 Power Classification: 2F Configuration: 0-6-0T Total Built: 10 Length: 27' 6" Width: 8' 8" Height: 12' 6.5" Weight: 43T. 12Cwt Coal Capacity: 1.5 Tons Water Capacity: 1000 Gallons Tractive Effort: 18400 Lbf Estimated Power Output: 450 HP Fire tube heating surface: 923 Sq Ft Firebox heating surface: 85 Sq Ft Total Heating Surface: 1008 Sq Ft Cylinder Size: 17' x 22' Driver Diameter: 3' 11" Boiler Pressure: 160 Psi Features included within the addon: Notched reverser with reverser catch Realistic steam brake Realistic reverser dynamics Working hydrostatic lubricator Improved gauge glass effects Improved wheelslip simulation Dynamic smoke & steam effects Regulator with steam chest effects Exterior animations (Windows/Regulator/Doors) Improved injector simulation Animated brake rigging www.MeshTools.co.uk 3 Controls Each engine has two versions, a standard [Std] and an advanced [Adv] version. The need for both arose when creating the script as we found that the AI simply could not drive the engine. In addition the loco brake did not function via the HUD. Since the HUD must be fully functioning we had to do two versions standard and advanced engines. The advanced version contains the advanced scripting which allows for better simulation of the vacuum brakes, two dampers, notched reverser, exterior animations and various other things like controlled emitters. This version is auto fireman compatible, but is not HUD compatible and is not AI compatible. The standard version has basically had the entire script removed. It is mostly designed for people who want to just hop in and drive without the fuss of notched reversers, vacuum brake leakage and so on. This version is also AI compatible unlike the advanced version. All scenarios have a standard and advanced version using the respective standard and advanced engines, allowing drivers of any skill to drive them without having any fuss and having to edit the scenarios themselves. 1. [STD] Standard mode with Auto-Fireman. 2. [STD] Standard mode with Manual Fireman. 3. [STD] Standard mode with Simple Controls. 4. [ADV] Advanced mode with Manual Firing only. The Regulator www.MeshTools.co.uk 4 The regulator controls how much steam from the boiler enters the cylinders; the further it is opened the faster you will accelerate. Essentially, if you want to move the locomotive you will probably want to open this, but be careful how much you open it since the engine may slip. The regulator can be controlled by using either your mouse on the regulator handle or the A and D key to respectively increase and decrease the regulator setting. The Reverser The next important control you will want to learn is the reverser, this works essentially like gears on a car. Moving the reverser closer to the centre is like moving up through the gears of a car meaning you can go faster. It works by limiting the amount of steam which enters the cylinder and allows the steam to expand more efficiently hence you will be able to go faster without emptying your boiler and making the fireman rather grumpy. To move the reverser you must first release the reverser lock by pressing E, then the W and S to move it forward and back. The reverser on the Dock Tank is of a pole type; it has 6 notches in either direction and a mid-gear notch. It is fitted with a locking mechanism which locks the reverser into a notch and prevents it moving while the regulator is opened. To release the lock the E key must be used, but caution must be used to not release the lock while the regulator is open more than a third otherwise the reverser could fly into full forward or reverse taking your arm with it! www.MeshTools.co.uk 5 Cylinder cocks The cylinder cocks allow any steam which has condensed in the cylinders to be exhausted out of the cylinder preventing damage since water can’t be compressed. A secondary effect of the drain cocks is that it aids warming of the cylinders when the regulator is opened. The drain cocks can be found under the reverser pole. The previous driver will have left the cylinder cocks open to prevent the engine moving while it stands idle (and so you don't forget to open them before moving off). The drain cocks should be opened when starting after being stationary for a prolonged period of time and left open for around 5-6 revolutions of the wheels. They are controlled by the C key. The Handbrake www.MeshTools.co.uk 6 Despite what some people may say the handbrake is the only truly failsafe brake and will probably work 99% of the time. But let's not worry about brake failures (they won't happen honest). The handbrake is less effective compared with other forms of braking being slower to apply, less effective and requiring the fireman to screw it down. It however doesn't require steam pressure to operate and hence will be your brake of choice when moving about the shed near the end of a long shift. Blower The blower is the left valve in the picture above. It is used to create a draught through the boiler when the regulator is shut; it's useful for creating pressure quickly when stationary ready for an assault on a hill! It does absolutely nothing when the regulator is open since that creates a draught as well, so it mainly just wastes steam. Make sure however it is open a bit when shutting the regulator and is wide open when going through tunnels to prevent a blowback of the fire into the cab, which would really ruin your day! To open and close the blower the N and shift N keys are used respectively www.MeshTools.co.uk 7 Sanders The sanders on the Dock Tank are of a steam type, and are bidirectional. Steam is used to force sand in front of or behind the wheels. Sand aids adhesion in poor railhead conditions. The handle has three positions: Up activates the forward sanders, horizontal stops both sanders and down activates the rear sanders. To move the handle up the X key is used while to move the handle down the Shift X key is used. Note: There is only a limited amount of sand so use it sparingly. There is enough sand to last for approximately 20 minutes in each direction so make sure you do not waste any! Injectors Injectors are used to put water into the boiler. Their operation is as follows: The water regulator is opened for the respective injector; this is located on the far left and right of the cab, being used for the left and right injectors respectively. This can also be open and closed by the K and Shift K keys for the left injector and L and Shift L for the right. Next, the steam valve is opened gradually to allow the injector to pick up. This can be done with the I key for the right injector and O key for the left; the same key is also used to turn them off. Remember to also open the water valve before starting the injector and after you have shut the steam valve otherwise steam will erupt from the injector and make a very loud noise! www.MeshTools.co.uk 8 Dampers On the Dock Tank there are two dampers; they are used to allow air into the firebox thereby heating up the firebox through improved combustion. They are located to the left of the firebox doors on the floor. To open and close the left damper the M and Shift M key are used, and for the right the Ctrl M and Ctrl Shift M keys are used. www.MeshTools.co.uk 9 Steam Brake The Dock Tank is fitted with a steam brake which operates on the locomotive only. It is not fitted with a vacuum brake so it will not be able to apply brakes on coaching stock and fitted wagons. The principle of the steam brake is that the higher the pressure of steam in the brake cylinder the greater the brake force will be. The brake valve on the Dock Tank has 3 positions; a release position between 0 and 10% of its travel where steam is rapidly vented from the brake cylinder, a hold position where no steam is allowed into or out of the brake cylinder, in this position the steam in the cylinder will slowly condense back into water, reducing pressure on the brake cylinder.
